Abstract: A THREE POINT LINKAGE                 ABSTRACT OF THE DISCLOSURE     A three point linkage for coupling a tractor or similar vehicle to a working tool includes two lower guide members and an upper guide member which is elastically connected to the lower guide members.  A catch hook is located at one end of each of the guide members for coupling to the working tool.  The other end of each of the guide members is coupled to the tractor.  The upper guide member is longitudinally adjustable and includes an inner guide element telescopically cooperating with a spring loaded outer guide element.  A nut, carrying pivotally movable locking jaws, is slidably carried on the outer guide element for fixing the outer guide element relative to the inner guide element.  The catch hook of the upper guide member is carried at the opposite end of the outer guide element from the nut.  A locking slide is axially displaceable on the outer guide element for locking a coupling bolt on the working machine within the catch hook and also for displacing the sliding nut in response to its contact with the working tool.  The locking slide has a first slot and the outer guide element is provided with a lug which has a second slot positioned at an angle with respect to the first slot.  A cross-bar passes through both slots so that the locking slide will be displaced when the cross-bar is moved within the slots.     Elastic struts connect the cross-bar with the lower guide members to achieve elastic coupling of the upper and lower guide members.          Longitudinal displacement of the slide relative to the outer guide element causes displacement of the sliding nut for releasing of the locking jaws and also for opening the catch hook to receive the coupling bolt of the working tool.

Abstract: ALARM CONDITION DETECTING APPARATUS AND METHOD                  ABSTRACT OF THE DISCLOSURE Alarm condition detecting apparatus in the form of a combustion products detection system for monitoring a zone to detect the occurrence of fire therein.  The apparatus has a plurality of detecting units adapted to be interconnected as parallel loads with a control unit.  Each detecting unit receives operating power which may be from the control unit and functions to monitor a selected portion of the zone, generating, as appropriate, condition signals indicative of condition normal, impending alarm, alarm or unit malfunction.  The impending alarm and unit malfunction signals are preferably pulsed signals of distinctly different frequencies and a light emitting diode (LED) arrangement is included in the detecting units to generate visual outputs corresponding to the impending alarm, alarm and unit malfunction signals.  The condition signals generated by the detecting units may be transmitted to and monitored by the control unit by the method of correspondingly changing the parallel load impedance thereacross to cause changes in a loop current flowing in the control unit. In response to such loop current changes, the control unit is adapted to appropriately indicate that the zone is in a normal state, an impending alarm condition, an alarm state, detecting unit malfunction or system trouble.  To indicate alarm condition, the control unit latches in an alarm output state.  The control unit has time delay circuitry to prevent latching into the alarm output state until an alarm condition signal of predetermined duration has been received.

Abstract: (U.S. 920,69 2) ABSTRACT OF THE DISCLOSURE          Impurities such as hydrogen sulfide and carbon dioxide are removed from fluids by contact with an aqueous alkanolamine solution which absorbs said impurities from the fluid.  The resultant spent absorbent amine stream is split into two streams;  one stream being routed directly to the top of an amine regenerator column and the second stream being routed to a heat exchanger where it is heated en route to an intermediate point of the regenerator column by heat exchange with the hot regenerated solution coming from the bottom of the regenerator column.  The spent amine stream which is passed directly to the top of the regenerator column is heated by condensing steam in the column which would normally escape therefrom.  Reducing the losses of saturation steam in combination with heating a portion of the spent absorbent amine stream by heat exchange with the hot regen-erated solution reduces the overall energy requirements for the system.

Abstract: DISPENSING CLOSURE FOR A SQUEEZABLE CONTAINER      ABSTRACT            A housing containing an annular tapered valve seat and mating valve secures the valve in fluid communication with the container interior.  Fluid in the container under pressure displaces the valve from its seat, flows through the interface between the valve and seat and is discharged to the ambient through a fluid passage coupled to the interface.  A shoulder in the housing engages a shoulder on the valve for limiting the displacement of the valve to a value sufficiently small to. retain fluid in the interface in the absence of pressure above ambient in the container.  The fluid in the interface acts effectively as a seal to ambient air so that a negative pressure in the container results in ambient air pressure forcing the valve to its closed position.

Abstract: ABSTRACT:      "Colour selection circuit for colour television".     A colour selection circuit for colour television, for example for chroma-keying signal generation. The signal generation is done independent of the luminance and depends only on the colour with which a given combination of input signals corresponds. This is effected by the use of an equal-signal detection behind amplifier circuits to which input signals, having a predetermined peak-peak value are applied and at least two of these input signals have been set with a given attenuation factor with respect to a third, which setting determines the colour at which the keying or switching signal is generated.
